Embodiment

[0081] This embodiment involves a specific day-end reconciliation-based distributed transaction double compensation method, image 3 A flowchart of the method is shown. The method mainly includes three steps:

[0082] Step 1: Normal processing, according to the principle of optimism, the business logic is gradually processed normally, and there is no need to think too much about transaction exceptions to avoid intrusion into the code. In the actual environment, most of the business can be processed normally and successfully, so most of the business only needs to be processed normally without compensation actions, which improves the overall performance of the business system.

[0083] Step 2: Real-time compensation. If an exception is encountered during normal processing, it needs to be rolled back across databases as a whole. For example in image 3 , the entire business process involves a total of 4 transactions and 4 databases. If transaction 1 and transaction 2 have bee...

Abstract

The invention provides a distributed transaction double-compensation method and device based on day-end account checking. The method comprises the following steps: performing normal processing on each transaction according to a business processing flow without considering the abnormal condition of the transaction; after the transaction is normally processed, submitting a database corresponding to the transaction in real time; if an exception occurs when the predetermined transaction is processed, performing real-time compensation on a database corresponding to each transaction before the predetermined transaction by adopting a real-time compensation mechanism; if the global transaction consistency principle is still not met after real-time compensation, carrying out daily end account checking compensation. And the consistency of a plurality of databases is ensured through a double-compensation mechanism of real-time compensation and day-end account checking compensation. And the balance between the real-time performance and the consistency of the transaction is realized. The scheme has the advantages of high efficiency, transaction real-time performance and low service code invasiveness.

Description

technical field [0001] The present application relates to the field of distributed transactions, in particular, to a method, device, computer-readable storage medium and processor for distributed transaction double compensation based on day-end reconciliation. Background technique [0002] When the business system uses multiple databases at the same time, it is necessary to coordinate multiple databases to ensure the global transaction consistency of the database, that is, distributed database transactions. Traditionally, there are many ways to solve distributed transactions, such as 2PC two-stage commit, TCC confirmation compensation, MQ message, etc. However, traditional distributed transaction solutions have disadvantages such as low real-time transaction performance, high intrusiveness to business code, and high development costs. . [0003] Specifically, traditional distributed transaction solutions have the following problems: [0004] 2PC two-stage compensation mech...
